Poker is a card game played between two to seven players. It is usually played with a standard 52-card deck, but can include one or more jokers or wild cards. It may be played with fixed or variable stakes, and the winner is determined by a combination of the highest ranking hands.
The first step to writing a book about Poker is to decide on the subject matter and focus. Once this is done, start keeping a file of poker hands that are relevant to your topic. These can be your own hands or ones you have found elsewhere.
You will also need to understand the rules of the game well, including all the different variants. You should be able to distinguish the differences between good and bad players, as well as their tells (unconscious habits that reveal information about a player’s hand). You will also need to keep up with the latest trends in poker, especially what happens in major casinos like those in Las Vegas or Atlantic City in the USA.
Another key point is to play within your limits. This means only playing games that you can afford and only taking risks you are comfortable with. If you are a novice, it is best to play in games with players at or below your skill level. This helps to avoid the temptation to take big risks which can quickly drain your bankroll. Eventually, you will build up your comfort with risk-taking by gradually taking smaller risks in lower-stakes games.
